X-Google-DKIM-Signature gets not DKIM verified by amavis

[Mark Schweizer]

Hello,

when using amavis 2.7.1-2 (debian) for DKIM verification, email-messages 
from Google with the header "X-Google-DKIM-Signature:" get not DKIM 
verified by amavis while all headers "DKIM-Signature:" get correctly 
DKIM verified.

Is it possible to use amavis for DKIM-verification of messages with a 
"X-Google-DKIM-Signature:" header?

Thanks for any comment.
